I know this is an old thread, however I have a working .conf file for the SMP-N100. I've had this working for over a year now and never posted it because honestly I never thought about it. It took me several hours of playing to get it to work, but it plays mkv, avi, mpeg, the whole nine. I've only come across a couple files it couldn't play out of over 250+ tested files. Please note, for "RendererIcon=D:\\Program Files (x86)\\PS3 Media Server\\sonysmpn100.png" I have my own icon, you may need to change this depending on your setup.

# Specs below taken from http://www.sony.co.uk/product/blu-ray-disc-player/bdp-s370#pageType=TechnicalSpecs# then fine-tuned by lengthy trial and error since so much of that advertised spec is inaccurate.# US models don't support video/divx mime type but European and Canadian models do.# Subtitles in mkv files are only displayed if mime type is video/divx.# Vob subtitles are not supported.# See also http://forum.serviio.org/viewtopic.php?f=11&t=2004 for more DLNA-related info on these players.
